Thanks Dave!

This is what is actually working for me thus far! At least some success:

Code:
INCLUDE "DT_INTS-18.bas"       ; Base Interrupt System
INCLUDE "ReEnterPBP-18.bas"     ; Include if using PBP interrupts

DEFINE OSC 20                           ' Running with a 20MHz x-tal
DEFINE HSER_BAUD 9600
DEFINE HSER_TXSTA 20h
